To be honest I don't see the downside in this situation. It seems that Witt had his ideas and Bo had other ideas. When it doubt, Bo is right. It isn't Witt's team. Even in the moments he got on the field, it wasn't as though a shiver ran through the stadium because we could see the superstar ready to explode. With the way the staff is going about the offense (and this goes all the way back to Tom Osborne's comments when he hired Bo to begin with), they want a mobile quarterback, and that will from this point on be a point of expectation for the position.
If Witt thought he could bluff Bo into naming him the starter out of fear of losing him, he apparently found out he was mistaken. Now we may have Lee for a couple of years, then Green after him. Maybe we get Green from the getgo--anything is possible. Either way, the reports all seem to indicate that Witt has some character issues and a me-first attitude about this thing. If he's not ready to fight to win the most prestigious position on the football field, it's probably better we don't give a position of leadership to someone like that. It sets a bad example.
In the end, though, many reports indicate Witt wasn't the best QB at the position anyway, so this whole thing is probably moot. We may have only just let a career backup walk out the door. Hard to say for sure, but as far as character goes, we might have just saved ourselves some real heartache down the road.
